Question
Download Solution PDFThe flywheel of a steam engine has a radius of gryation of 1 m and mass of 2500 kg. The starting torque of the steam engine is 1500 Nm and may be assumed constant. The angular acceleration of the flywheel is _______.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
The torque is given by the relation
T = Iα
where 'I' is the moment of inertia and 'α' is the angular acceleration in rad\s2.
Also, I = mk2
where 'm' is the mass and 'k' is the radius of gyration.
∴ T = mk2α
Calculation:
Given:
m = 2500 kg, k = 1 m, T = 1500 Nm
T = mk2α
∴ 1500 = 2500 × 12 × α
α = 0.6 rad/s2
